SCC Equivalent Resistance: the Relationship for Complementary Buck and Boost and Accurate Calculation for 2-Phase Converters

Abstract

This paper makes the following contributions to Switched Capacitor Converter (SCC) equivalent (output) resistance analysis. First, it suggests the relationship between equivalent resistances of complementary buck and boost SCC: equivalent resistance of a boost SCC equals that of its buck counterpart times squared boost voltage Target Ratio (Voltage Conversion Ratio). Another contribution is equivalent resistance accurate calculation methodology for an arbitrary 2-phase SCC.
